Welded yeeb nkab nto quenching thiab tempering kho cua sov feem ntau yog ua los ntawm induction cua sov los yog nplaim hluav taws kub.Lub ntsiab technical parameters yog deg hardness, lub zos hardness thiab zoo hardening txheej tob.Kev ntsuas hardness tuaj yeem siv Vickers hardness tester, tuaj yeem siv Rockwell lossis nto Rockwell hardness.Qhov kev xaiv ntawm kev xeem quab yuam (scale) muaj feem xyuam rau qhov tob ntawm cov txheej txheem hardened zoo thiab qhov hardness ntawm cov yeeb nkab welded.Ntawm no muaj peb hardnesses.
